Answer:The plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually transmitted to humans through fleas.

The risk of plague is highest in areas that have poor sanitation, overcrowding, and a large population of rodents.

In medieval times, the plague was responsible for the deaths of millions of people in Europe.

Today, there are only 1,000 to 2,000 casesTrusted Source reported worldwide each year, with the highest incidence in Africa.

Plague is a rapidly progressing disease that can lead to death if untreated. If you suspect you have it, call a doctor right away or go to an emergency room for immediate medical attention.

Types of plague

There are three basic forms of plague:

Bubonic plague

The most common form of plague is bubonic plague. It’s usually contracted when an infected rodent or flea bites you. In very rare cases, you can get the bacteria from material that has come into contact with an infected person.

Bubonic plague infects your lymphatic system (a part of the immune system), causing inflammation in your lymph nodes. Untreated, it can move into the blood (causing septicemic plague) or to the lungs (causing pneumonic plague).

Septicemic plague

When the bacteria enter the bloodstream directly and multiply there, it’s known as septicemic plague. When they’re left untreated, both bubonic and pneumonic plague can lead to septicemic plague.

Pneumonic plague

When the bacteria spread to or first infect the lungs, it’s known as pneumonic plague — the most lethal form of the disease. When someone with pneumonic plague coughs, the bacteria from their lungs are expelled into the air. Other people who breathe that air can also develop this highly contagious form of plague, which can lead to an epidemic.

Pneumonic plague is the only form of the plague that can be transmitted from person to person.

How plague spreads

People usually get plague through the bite of fleas that have previously fed on infected animals like mice, rats, rabbits, squirrels, chipmunks, and prairie dogs. It can also be spread through direct contact with an infected person or animal or by eating an infected animal.

Plague can also spread through scratches or bites of infected domestic catsTrusted Source.

It’s rare for bubonic plague or septicemic plague to spread from one human to another.

<h3>What is fitness?</h3>

<u>Fittest </u>is the term describes living things that are best suited to their environment.

Species that survive are the ones that <u>adapt</u>, make or meet changes.

Florida has a rich <u>fossil </u>record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the <u>giant sloth</u> and the<u> </u><u>saber-tooth tiger</u>.

Some animals unable to adapt to the changing environment became <u>extinct </u>.

Living things <u>mutate </u>over time to meet their changing environment.

This biologist, Darwin, studied <u>evolution </u>in the 1800s.

The <u>glyptodont </u>was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about<u> </u><u>natural selection</u>.

Nature selects the <u>fittest </u>for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a <u>mutation</u>.

Oldfield mice show <u>variation </u>in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called <u>adaptation</u>.

Evolution is a controversial theory that has survived much <u>criticism</u>.

1. In which way does the circulatory system rely on the skeletal system? (1 point)
german

Answer:

The correct option is Blood cells are produced in bone marrow.​

Explanation:

Skeletal system can be described as the system which comprises of all the bones and joints of an organism. The main function of the skeleton system is to provide support and protection to the organism.

The circulatory system can be described as a system which comprises of the heart, blood vessels and blood. This system is mainly involved in the transportation of substances like oxygen, nutrients etc in the body.

The skeletal system interacts with many other systems of the body and helps them perform their functions. For example, the skeletal system interacts with the muscular system so that a muscle can contract and relax.

The skeletal system interacts with the circulatory system by producing blood cells in the bone marrow. Red blood cells, as well as white blood cells, are produced by this process.
